3 Claims.` (Cl. 126-498) experienced in broiling because thethermostatic V control device, acting in response to arise in theunderside of the insulated top panel IIvso as temperature in the bakingoven, will'reduce the supply of gas to the burner before the broilingoperation has been completed.

The present invention has for its object the provision of a stop deviceof a simple and inexpensive construction shiftable from a normalout-of-the-way position to a position in which it is operative to -holdthe door of the baking oven tively according to the length or intensityof the broiling operation. performed, especially under conditions whenit is desirable to limit the escape of heat into the roomto' an amountwhich is suilicient only to render the thermostat inoperative to reducethe gas supply.

The objects of the invention thus generally stated, together vwith otherand ancillary advantages, are attained by the construction andarrangement shown by Way of illustration in the accompanying drawingsforming a part hereof, in which:

Figure 1 is a fragmentary vertical sectional view through the upperportion of a baking oven of a gaseous fuel stove and showing my improvedstop device swung into position to hold the door in the outermost one ofthree positions.

Fig. 2 is a. similar view but showing the stop Y device in its normal orinactive position within the oven.

Fig. 3 is a fragmentary horizontal sectional view taken approximately inthe line 3-3-of Fig. 2.

In carrying out my invention, I provide a stop device consisting simplyof a sheet metal stamping or plate I mounted on a fixed pivot 8 forrotational movement from a normal inactive position within the oven intoa projecting position With respect to the front opening S of the oven.In its projected position, the device forms an abutment operative toheld partially open the oven door IIl which is hinged in theconventional way and biased toward closed position.

Preferably, the stop plate 'I is mounted upon to be substantiallyconcealed from view when not in use and it is disposed adjacent thefront opening 9 substantially centrally of the latter. As shown, thepivot 8 is mounted in the inner lining I2 of the top panel I I whichlining forms the top wall 'of the'oven compartment. It is retained inposition by means of a washer I 3, the plate I being interposed betweena head I4 on the pivot pin and another washer I5. Thel washer I3 is oi'a well knownconstruction capable of exerting an axial upward thrust onthe pivot pin which t'ends to bind the stop plate between the head I4 ofthe pivot pin and the washer I5, thereby retarding rotational movementof the stop plate.

In the present instance, the stop plate has three stop fingers, I6, I1and I8, of varying length and spaced apart circumferentially asuiiicient distance to permit of independent action. As shown in Fig. 1,the longest stop nger I8 is in active position forming an abutment forengagement by the upper edge portion of the door I0. By turning thestopplate counterclockwise (Fig. 3) approximately forty-five degrees,the next shorter stop nger I'I will be placed in active position.Similarly, another rotational movement of approximately forty-fivedegrees in the same direction will bring the shortest stop ringer I6into operative position.

It will be understood that one /or the other oi.' the several stopfingers is moved into active position, according to the length orintensity of the broiling operation to be performed or in accordancewith other conditions such as the room temperature or the temperature ofthe baking oven at the time the broiler operation is started. When notin use the plate is turned to the position shown in Fig. 1.

I claim as my invention:

1. In a gaseous fuelcook stove comprising a' baking oven having atoppanel with an inner lining forming the top wall of the oven, a frontopening and a hinged door for said opening biased toward a closedposition, a stop plate, a headed pivot pin carried by said inner liningand rotatably supporting the stop plate at the upper edge of saidopening, said stop plate having a portion swingable into a positionprojecting through said front opening for engagement with the upper edgeportion of the hinged door to hold the same in partially open position,and said pivot pin having means associated therewith and with saidlining acting to exert an axial thrust on the headed pin so as to holdthe plate frictionally against rotational movement.

ing for engagement with the door to hold the 10 latter in partially openposition'.

3. In a gaseous fuel cook stove having a baking oven with a frontopening and a hinged door for said opening biased toward a closedposition, a stop device rotatably mounted within the oven compartment onan inside wall thereof, and means acting to frlctionally retard therotational movement of the stop device, said stop device having aplurality of spaced fingers of varying lengths selectively swingableinto a position forwardly of said opening for engagement with the doorto hold the latter in partially open position.
